using CSMA/CA based contention avoidance schemes. The network layer incorporates the routing
protocol, which will be selected from the existing routing
protocols for WSN with characteristics suitable to the PF
application. The application layer involves the commands to
read the sensed values with a specific rate and request from
the lower layers to send it also with a specific rate or on special
events. The overall architecture of the proposed solution
formed by having a number of scattered sensor nodes with
the previously stated architecture communicate wirelessly to
a base station connected to the local or remote user application
which receives the network data and appropriately process it.
